Forensic teams will continue combing thick scrub near Wollongong after finding human bones, believed to be those of a Vietnamese businessman who went missing in Sydney more than four years ago.
Minh Phuoc "Paul" Nguyen was last seen driving out of the Hilton Hotel in the CBD in a luxury golden hire car on the night of May 1, 2014.
NSW Police suspect the 50-year-old was later murdered at a Bankstown unit block where a blood stain was found on the carpet.
Two men were charged in 2015 over the murder of Mr Nguyen, who had underworld links.
Acting on information received, strike force detectives, along with the Public Order and Riot Squad, the Dog Unit, the Rescue and Bomb Disposal Unit and local police kicked off a co-ordinated search of bushland at Cordeaux on Tuesday morning.
Teams will continue searching for more remains on Wednesday and other items of interest, police say.
The bones found on Tuesday will now be forensically examined to determine the identity.
Until now, neither Mr Nguyen's body nor his hire car have been found.
A search of a motel room in Casula, in Sydney's southwest, three days after his disappearance uncovered an airline boarding pass.
Police have previously said Mr Nguyen's associations with organised crime may have made him a target.
The Vietnamese migrant had only just reconnected with his three brothers and sister after becoming estranged from them when he moved to Australia in his 20s.
In 2015, a 23-year-old Casula man was charged with his murder and a 19-year-old from Liverpool was charged with being an accessory after the fact.
